"Be it known "that 1, Gmonon E. Ammnson, a citizen of-the United-States, r'esidin at Ohic'ago, in the county-of Cook and tate of Illinois, have invented a certain new and useful 1m rovement in Combinationwrenchesyof w I ich the following is a specification.

I This invention relates-t wrenches and its object is 'twprovide awi'ench by which -11 Bhu'ft,'='boit*0r screw-mem'fiber and a nut thereon may each be independently engaged by the wrench 'mechanismend either one of =-berotated as desired.

The invention consists-in e device cepable-of-carrying out thisobjectwhich is neat and compact 1n ierm, -end can-be conveniently made (and operated.

- More -detai1 Bheinventien consists in means by which one if "the rope: be rigidly connectedto theot er' i'n d" erent positions "whereby the ()Yel'iltlllg may ectiyely p' rete 'either'wrench.

' Referring egam te the-him le form of constfiuctiom -e cylindrical she t 12 is proof .a :pin'14, afomnkerm 16 and ha'ndle 18. *The oppoeitee'nd of-this shayft '12 carries a cylindr cal-enlargement or-flange 20 in the interior of which isfa-men-eircular; in the particular instance he' reshowna square, hole 22 adepted to act ee a wrench when in 81-1-- me'nt with a comes nd'ingly shaped en '24.- on the shaft 26. I his shaft beyond the left of the figure and'notehowm mey-be "either an ordineryeheft, bolt Or n-screw! deeired it forms no partedfthe invention.

Journaled u ,on this she-ft '12 between the-- flange 29 en the crank arm 16 ism; tubular, member 28, whose'outer or'le'ft hand end, as,

shown in *the drawing; carries anenla rge T 'ment 30 within which is formed a non-circ'tflar, in the particular ,inetence here shown a square, 0 ning 32 adaated a nut I 34 mew t reede'd at 8 ;-upon the s heretofore described. Rigxdly-cennected to"- en es this tubular member 28 by screw; threads-'38 or any other suitable meane is a wrenchhand-le 40. The -fit between eoller- 28"-end=*the rod or eheft leis loose enough'ee that either enough apart so that the 'neer take hold of the handle'O Without danger of-injnr ing his hand or fingers by. contact withthe'crank 111111'16 as=eithefm1e of these members is -ro-" bated. "The-result of this construction is that when thesimple-wrench :dev i'ceof- Figs. "1, Quid-Bis appl1ed-to theT ertssho'wn in Fig.4, *thein'terior socket engages the non rcir'culaf portion 24 of the shaft 26 while the exterior fso'c'ket BQ eng'egeS the nub-34.- and the flperatonmey ifdeeited hold the handle '40. stationary and by the use f'of ithe handle 18 rotate interior wrench, thusrotating :the shaft 26 while the 'nut 34 re .ma'ins stationary, 01 he may, by =holding=the handle 18 stationary and rotating the-handle 40, moveflhehntfl upon :the stationerilrheld shaft 26. The two sockets' being concentric and mounted in one tool, the 'device has the distinct advantage of doing away with the use of two tools, which h'eve heretofore been necessary and greatly simplifies the work required and the'amount of attention required in manipulating-the nut 34 'with reference to the, shaft 26 or vice verse.

In the modified'ioi m of'the device shown in Figs. 6 to "10 inclusive, a shaft 44 is provided with an operating handle 46 like han-- dle'16-18 and at the opposite end ofthe sha-ft 44 is an interior-non-circularzsocket opening 48 correepondingto'the opening-22 hon-circular end 50 of the shaft 52. The

- outer circumferential surfaceof the nut 54 is. made non-circular, in the particular in- I stance here shown square, as best seen in Figs. 7 and 9, so as to fit into a corresponding socket opening or recess 58 formed within theouter wrench member 60, which is, in this form of the device, made rather short and thick, as bestseen in Figs. 6 and 10, andjournaled upon the shaft 44. Rigidly secured to thisouter wrench member 60, by

any. suitable means, is a handle 62, corre- -.sponding to the handle 40. Within this -.ha1 1dle 62 is a latch pin or rod 64 normally urged upward when viewed as Fig. 6 by spring 66, adapted to enter an annular groove 68formed in the circumference of the rod ,44 ;at the position shown in Fig. 6 wherein a the two parts of the wrench simultaneously ;engage the member and the nut 54 as -,-lshow.n;gexactly as the wrench of Figs. 1, 2

do? engages the parts it is designedto per gate. This groove 68'is of sufficient size *1 I. s

that the" end of the pin 64 enters it g looselyv and doesnotinterfere with the ready .-;'IQi ;iQ f r of-either the wrench members 60 or 1n;e2;%ctly the same manner as the parts thegpreferred form of the wrench are operated.-.,- ;Parallel with this annular groove .;6 8-.an' d at a distance therefrom are-two rows ;of:; circular holes Z0 and. .72 respectively,,,ex-

tending around the circumference of the shaft 44, and in which 'the.endzofthe'jrod 64 may-be,selectively inserted; The row of holes 70;. is, as showncin'F-ig. 10, at such a posit on that when the wrenchmembQr 60 is movedforward or to the :left in Fig. 6, v:to

.itherposi tion shown"- inwFigZ 10, and the pin G4:lS"i1-1S It6d;ill-30118 of the holes/70., the

:wrench member w-60lwill therefore be rigidly looked upon the rod in-the position shown in which, when: the outer. wrench member 60 is applied to .the nut-54, the-inner wrench :-;member.- docs-not'engageat-all the member 52, withflthe result: that the operator =may rotate the handle46 a reasonable substantia-l distance at least, without any interference or obstruction by. the member 50. The

row of holcs 72 is so. located that when the 50111181) wrench member 60is moved toward '-..;tl 1e right in. both-Figs. 6 and 10 until the 1:111:64 engages one of the ho1es72, theouter wrench-member issufliciently far back upon aboutthe first member, and an in carried rotating mechanismfor detachably locking-thebearthe rod 44 so that the operator may, by the use of the handle 46, use the inner wrench member to rotate the shaft 52 without the outer wrench member coming in contact with the nut 54. The outer wrench member 60 isprevented from drop in off the shaft 44 by the use of the flanged cofiar 76.

It may be properly stated that this device is primarily designed for use in connection with a school desk wherein the shaft 26 or 52 operates an elevating mechanism controlling a part of the desk and the nut 34 or 54 serves, the purpose ofv locking said I shaft and attached parts in adjustable position, all asmore fully appears in a patent application for such'a desk filed herewith, Serial No. 486,974, but the deviceis manifestly capableof use in many other sorts of mechanisms.

The word socket is used in the claims to cover and include any sort ofno'ncircular form or device adapted to engage with a corresponding-part on an adjacent bolt, nut, shaft, tube, or the like.

What I claim as new, and desire to secure by Letters Patent, is:

1'. A wrench comprising one socket mem-' her a handle-for rotating the same, a second socket member concentrically (iournaled ependent handle engagingt-he second so'cket member for controlling 1t. v

2. In a mechanism of the class described, the combination of a shaft carrying at one end a socket and at the other end meansfor rotating it, a: bearing block rotatably and slidably mountedupon the shaft, a socket member carried by the bearing block, means for rotating the bearing block about the. shaft, and mechanism for detachablylockin the bearing block-in selected longitudina position upon the shaft while permitting rotation thereof.

3. In a device of the class described, the

. combinationof twoconcentric members each provided with sockets ada ted to engage different objects, a journal earing' between the two memberswherebyeither may @be rotated with reference to the other, "rude .pendent mechanismsfor operating each of the socket members,; and means fore-detach ably locking the two by rotating either socket wi-l rotate the sockets to ether where- Other.

4.
